The CBI probing the Saradha scam was preparing to file a supplementary chargesheet sometime next week incriminating a number of Trinamool Congress top guns including Ministers and MPs sources said. When asked as to whether the names of Jailed State Minister Madan Mitra and MPs Srinjoy Bose’s names would figure in the chargesheet officials said such names were indeed likely to figure in the document to be placed before the Alipore Court. The chargesheet could show the influential persons as “main conspirators” in the scam alongside Sudipto Sen, Kunal Ghosh and Debjani Mukherjee. The Agency will file its supplementary chargesheet in the Saradha Realty case a source said.
